Write an addition expression to describe each situation. Then find each sum.

If $20.00 was spent on Shoes, what was the total amount spent on the shopping trip?

Ahat [919]

Answer: Total = $200

Step-by-step explanation:

Given information

Money spent on shoes = $20.00

Percent of Money spent on shoes = 10%

Given formula

The total amount of money spent × Percent = Money spent on shoes

⇵

The total amount of money spent = Money spent on shoes / Percent

Substitute values into the given formula

The total amount of money spent = Money spent on shoes / Percent

Total = (20.00) / (10%)

Convert percentage into decimal

Total = 20.00 / 0.1

Simplify the fraction

$\Large\boxed{Total~=~200~Dollars}$

Hope this helps!! :)

Which binomial is a factor of 8x^2y^3-18y

Musya8 [376]

Answer:

Please check the explanation.

Step-by-step explanation:

Given the expression

$8x^2y^3-18y$

Apply exponent rule: $a^{b+c}=a^ba^c$

$8x^2y^3-18y=8yy^2-18y$ ∵ $x^2y^3=yy^2$

$=4\cdot \:2yy^2+9\cdot \:2y$

Factor out common term 2y

$=2y\left(4x^2y^2-9\right)$

We know that the Binomial is an expression that consists of two terms. Thus,

(4x²y²- 9) represents the binomial factor of $8x^2y^3-18y$

We can further simplify by Factoring 4x²y² - 9: (2xy + 3) (2xy - 3)

$=2y\left(2xy+3\right)\left(2xy-3\right)$

Here:

(2xy + 3) and (2xy -3) are the binomial factors of $8x^2y^3-18y$ as each of them consists of two terms.

A company has found that the daily demand x for its boxes of chocolates is inversely proportional to the price p. When the price

Amiraneli [1.4K]

Answer:

667 boxes

Step-by-step explanation:

-Given that x is the demand and p the price.

-Let k be the constant of proportionality. We then express the inverse relationship as:

$x=\frac{k}{p}\\\\k=xp=800\times 5=4000$

#We substitute for the new x value and the calculated k to solve for p:

$x=\frac{k}{p}\\\\p=\frac{k}{x}\\\\=\frac{4000}{6}\\\\=666.6667\\\\\approx 667\ boxes$

Hence, the demand at a price of $6 is approximately 667 boxes

kolezko [41]

Answer:

4%

Step-by-step explanation:

Given data

The total sales= $8900

Donated amount=$356

Hence the percent donated is

=Donated amount/Total Sales *100

= 356/8900*100

=0.04*100

=4%

Hence the donated percent is 4%
